The invention relates to the technical field of underwater detection, in particular to a buoyancy adjustment device. A snorkeling device for a submarine sonar robot, comprising: a support frame and a connecting rod, a support plate is installed inside the support frame, an upper pressure plate and a lower pressure plate are arranged outside the support frame, and the lower pressure plate is connected to the bottom edge of the support frame, And the gear belt is driven by a drive motor installed on the outer wall of the support frame. In the present invention, by setting the upper and lower corresponding upper and lower pressing plates on the outer side of the support frame, and setting the screw rod and the threaded cylinder between the upper and lower pressing plates, the distance between the upper and lower pressing plates can be freely adjusted according to the needs, and the robot can be provided with buoyancy of different sizes. Improve the applicability and stability of the device; in addition, the present invention can reduce the difficulty of connecting the device to the robot by installing a docking plate on the inner wall of the robot, and setting a docking pin opposite to the docking plate on the inner side of the support frame, and can also improve the device. The stability of the connection with the robot.

The invention discloses an efficient volleyball auxiliary training device for sports. The device comprises two fixing frames which are parallel to each other. A plurality of parallel guide rails are arranged between the fixing frames. The guide rails are perpendicular to the fixing frames. The two ends of the guide rails are fixedly connected with the corresponding fixing frames at the same time. Movable seats are movably arranged on the periphery of the guide rails. Motors are fixedly arranged in front of the movable seats respectively. Rotating discs are fixedly arranged at the output ends of the motors respectively. Cylindrical grooves are formed in the outer sides of the rotating discs respectively.
